Dark Web Profile: Red Ransomware

Red Ransomware Group’s Wall of Shame

Who is Red Ransomware

Red Ransomware or Red CryptoApp, a fresh ransomware group, surfaced in March 2024 and promptly revealed the data of 11 victims on its Data Leak Site (DLS), along with announcing an additional victim.

Their DLS debuted on March 29, 2024, titled “Wall of Shame.” Interestingly, the group chose to release the data of all 11 victims simultaneously on March 5, 2024, indicating a strategic delay in publishing the information. This tactic hints that Red CryptoApp probably have initiated their activities earlier and deliberately held off on disclosing the data for a greater effect.

Victimology

The victimology report for Red Ransomware reveals a narrow range of targets across a few sectors and countries. The majority of victims, mainly in the United States, represent industries such as Information Technology, Legal, Hospitality, Transportation, Manufacturing, Education, Electronics, and Retail.

This narrow targeting could indicate Red Ransomware’s focused approach, possibly because of lack of wide capabilities. The overview also notes a recent victim in the Retail sector from the United States, indicating that the group’s activities extend beyond its initial incident on March 5, 2024, showcasing ongoing threats posed by Red Ransomware.

The inclusion of victims from Canada, Singapore, Mexico, Spain, Italy, India and Denmark shows the narrow international reach of the Red Ransomware group. Most Western affiliated countries and heavy targeting US, also show a classical ransomware approach.

Modus Operandi

There isn’t detailed incident analysis for public research other than Rakesh Krishnan at Netenrich shared. The known facts are detailed below:

Infection Method:

Red Ransomware infects systems by exploiting vulnerabilities or using phishing emails with malicious attachments. Once a system is compromised, all files are modified with the .REDCryptoApp extension, rendering them inaccessible.

Target Selection:

1. The group targets a wide range of industries, including Information Technology, Legal, Hospitality, Transportation, Manufacturing, Education, Electronics, and Retail. This broad targeting approach aims to maximize impact and financial gain.
2. Timeline of Operations:
   • Mid-February 2024: Initiation of targeting efforts, as indicated by the ransom note’s date of February 18, 2024.
   • Early 2024: Intensification of operations, leading to the leakage of victim data in March 2024.
   • April 19, 2024: Ongoing activities evidenced by a new victim in the Retail sector from the United States.

Victim Interaction:

3. Red Ransomware provides victims with a unique TOR URL to facilitate negotiations. Victims access a login panel titled “Company Recovery,” where they input their unique “Hash” ID and solve a captcha to access the chat window.

4. Chat Interface:
   • Left Pane: Displays crucial victim information, including Victim Name, Negotiation Timeframe, Ransom Demand, Data Size, and Bitcoin Wallet Address.
   • Right Pane: AI-generated text is utilized for communication, indicating the group’s adoption of AI tools.
5. Ransom Demand:
   • In one instance, a ransom demand of $5 million was observed, showcasing the group’s substantial financial demands.

Use of AI Tools:

6. The use of AI-generated text in communications serves as concrete evidence of Red Ransomware’s utilization of AI tools, highlighting the evolving sophistication of ransomware operations.

Global Impact:

7. Red Ransomware’s victims span across various countries, including the United States, Canada, Singapore, Mexico, Spain, and Denmark, demonstrating an international reach that is not that wide for now.

Latest Victim

Red Ransomware group featured Targus on its dark leak site “Wall of Shame,” displaying a red “Coming Soon” banner beneath the company’s name in early April and now its data has allegedly been published.

SEC Filing by the company

On April 8th, Targus’ parent company, B. Riley Financial, submitted an 8K breach disclosure to the US Securities and Exchange Commission (SEC). The Los Angeles-based financial investment firm, which acquired Targus in October 2022, revealed that an unauthorized threat actor gained access to certain file systems on April 5th.

Upon detection, Targus promptly shut down its systems to mitigate damage and isolate the attacker. B. Riley noted in the SEC disclosure that while this action temporarily disrupted business operations, external experts were already engaged in restoring the compromised systems.

The filing did not specify whether B. Riley was aware of the identity of the attackers or the duration of their presence within the network. Furthermore, details regarding the affected systems or the extent of data compromise were not disclosed in the filing.

But it has definitively shown that this small-scale and seemingly not very sophisticated group can cause real harm.

Conclusion

Red Ransomware’s modus operandi encompasses somewhat regular infection methods, narrow industry targeting and international operation. The integration of AI tools in victim interactions and combination of regular tactics underscores the group’s novice capabilities but still highlights the ongoing threat posed by ransomware groups in the cybersecurity landscape.
